Hopefully most of us will go throughout life without being tracked by a GPS bug, but if you're worried that someone may be following your whereabouts with technology there are common places you can look to find the device. Security and investigations expert Brandon Gregg offers up a few suggestions to help you discover these bugs.

Brandon's answer comes from a question on Quora and provides plenty of detail, but here's the gist:

You should first look thoroughly at the underside and trunk of your vehicle. Many older tracking devices are large and magnetic, so they're most quickly and easily placed in these areas. (In some cases they'll be taped on or adhered in another manner if they can't be attached magnetically.) GPS signals are also well-received near the road's surface, so placing the devices beneath your car can help to ensure that the signal is received.

While the device may be very large and obvious, keep an eye out for anything as small as the size of a pager. While this may seem like a difficult search, the devices tend to stick out and you shouldn't have too hard of a time noticing them.

In the event that your car was impounded, stolen, or there are strict GPS laws for law enforcement where you live you will need to be more thorough. Smaller and more expensive GPS tracking devices can be hard-wired into your car's battery and hidden almost anywhere. To find them, you'll likely need to enlist the aid of a Technical Surveillance Counter Measures (TSCM) device (like these). They're very expensive, but will get the job done.

Chances are that most of us won't find ourselves in a situation where we need to seek out and remove a GPS tracking device, but if you do now you'll know where to look. Fore more detail, be sure to read Brandon's full answer over at Quora.
